The incorporation of the trifluoromethyl group into organic molecules has becoming a hot topic, as trifluoro-methylated compounds possess unique physical properties and biological activities. The catalytic cycle may involve a cationic intermediate whose stability was effected by the substituents on the aromatic ring and that the process of generating this cationic intermediate may be the rate limiting. To demonstrate the scalability of this protocol, the reaction was carried out on a mole scale under the standard reaction conditions. The reaction could also be obtained with a moderate yield. Control experiments indicated that both light and photocatalyst were essential to the success of the tandem trifluoromethylation/arylation reaction.

Photoredox catalyzed C(sp3)[sbnd]C(sp) coupling of dihydropyridines and alkynylbenziodoxolones

A visible light mediated deformylative alkynylation of aldehydes is presented. Under photo irradiation, 1,4-dihydropyridine (DHP), derived from an aldehyde, generated a C(sp3)- radical which couples with an alkynylbenziodoxolone to generate an alkyl substituted alkyne coupling product. This strategy is mild and easy to operate, a wide range of functional groups were tolerated, and 16 examples of products with 35?86% yields were obtained.

Host materials with pentafluorophenyl substitution are described. These compounds are designed for, and used for hosting aza substituted dopants that may be susceptible to intramolecular deprotonation. In addition, the fluorinated substitution aids with electron transport within the emissive layer.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Electric Literature of 94928-86-6, you can also check out more blogs about94928-86-6

Effect of substitution of methyl groups on the luminescence performance of IrIII complexes: Preparation, structures, electrochemistry, photophysical properties and their applications in organic light-emitting diodes (OLEDs)

A series of dimethyl-substituted tris(pyridylphenyl)iridium(III) derivatives [(n-MePy-n?-MePh)3Ir] [n = 3, n? = 4 (1); n = 4, n? = 4 (2); n = 4, n? = 5 (3); n = 5, n? = 4 (4); n = 5, n? = 5 (5)] have been synthesized and characterized to investigate the effect of the substitution of methyl groups on the solid-state structure and photo- and electroluminescence. The absorption, emission, cyclic voltammetry and electroluminescent performance of 1-5 have also been systematically evaluated. The structures of 2 and 4 have been determined by a single-crystal X-ray diffraction analysis. Under reflux (> 200 C) in glycerol solution, fac-type complexes with a distorted octahedral geometry are predominantly formed as the major components in all cases. Electrochemical studies showed much smaller oxidation potentials relative to Ir(ppy)3 (Hppy = 2-phenylpyridine). All complexes exhibit intense green photoluminescence (PL), which has been attributed to metal-to-ligand charge transfer (MLCT) triplet emission. The maximum emission wavelengths of thin films of 1, 3, 4 and 5 at room temperature are in the range 529-536 nm, while 2 displays a blue-shifted emission band (lambdamax = 512 nm) with a higher PL quantum efficiency (PhiPL = 0.52) than those of complexes 1 and 3-5; this is attributed to a decrease of the intermolecular interactions. Multilayered organic light-emitting diodes (OLEDs) were fabricated by using three (2, 3 and 4) of these IrIII derivatives as dopant materials. The electroluminescence (EL) spectra of the devices, which have the maximum peaks at 509-522 nm, with shoulder peaks near 552 nm, are consistent with the PL spectra in solution at 298 K. The devices show operating voltages at 1 mA/cm 2 of 4,9, 5.6, 5,1, and 4.6 V for Ir(ppy)3, 2, 3, and 4, respectively. In particular, the device with 2 shows a higher external quantum efficiency (etaext = 11% at 1 mA/cm2) and brightness (4543 cd/m2 at 20 mA/cm2) than Ir(ppy)3 (etaext = 6.0% at 1 mA/cm2; 3156 cd/m2 at 20 mA/cm2) and other Ir(dmppy)3 derivatives, (dmppy = dimethyl-substituted ppy), under the same conditions. The methyl groups at the meta (Ph) and para (Py) positions to the Ir metal atom have a great influence on absorption, emission, redox potentials and electroluminescence. Wiley-VCH Verlag GmbH & Co.

Effect of metal ion substitution on the catalytic activity of a pentanuclear metal complex

A pentanuclear cobalt complex that consists of five cobalt ions and six bpp- ligands (Co5, Hbpp = 3,5-bis(2-pyridyl)pyrazole) was synthesized and crystallographically characterized. Electrochemical measurements indicate that Co5 has multielectron transfer ability. We also found that Co5 reduces CO2 to CO under photoirradiation in the presence of a photosensitizer.
